To all whom it may concern;

Be it known that l, Gnonen denser lhron, a citizen of the llnited States, and resident of Philadelphia, county of Philadelphia, and

ill

iii

State of Pennsylvania, have made a certain new'i a'nd useful lnvention Relating to Channelldar ,illutomobiledBuders, of which the following is a specification, taken in connection with the accompanying drawing, which forms part of the same,

This invention relates especially to auto mobile bufiers having angular or channel bumper bars and adjustably connected sup porting members which may be conveniently formed of vertically rigid spring steel strip 'lhese supporting members may comprise at taching members to be clamped or otherwise connected to the automobile frame, and outwardly curved resilient portions, and are preferably provided or formed with bent connector portions or loops'which may have their strip edges clamped to the bumperbar. 'llhese connector loops may be substantially closed and provided with connector apertures, one or more connector bolts preferably extending through each of these connector loops and through connector openings such as holes or slots in a flange of the bumper bar and also through suitable nuts cooperating with the connector loops so as to securely clamp the connector loops of the sup porting members'to oneof the flanges ofthe bumper bar. In this way also a convenient adjustment can be secured, rendering the buder laterally adjustable as fares its sup" porting or attaching members are concerned, so that it can fit automobiles having frame members at di d'erent distances apart.

lln the accompanying drawing showing in a somewhat diagrammatic Way illustrative embodiments of the invention,

The bumper bar of'any desired angular or channel section may as indicated in Pig. l"

have rearwardly curved ends and may comprise the web it and flanges 2, 8, ill series of connector holes, such as a, may be formed. 1n one of the flanges adjacent each end of the bumper bar and for most purposes these con nector holes are preferably formed in the lower flange so that the connector devices are til concealed and protected to a greater extent" Resilient supporting members may with advantage be formed of spring steel strip of considerably greater vertical width than thickness so as to secure the desired vertical rigidity while rendering these supporting members many times more yielding in horinontal directions. The supporting members mavcomprise the rearwardly extending at tac mg members 5, 6 to be clamped or otherwise secured to the frame of the automobile or other vehicle. Each of the supporting members is preferably formed with an outwardly curved resilient portion in and with a connector loop or portion adapted to be glamped to one of the flanges of the bumper ar, loop may comprise the cooperating bent portlons t, 8 and 9 forming a connector loop of such width as to accommodate the connector bolt 10 and be located and preferably concealed within the flanges of the bumper bar, Per some purposes in order to somewhat stid'en this connector loop the end of the supporting member strip 9 may be brought out into substantial contact with the bend or curve '71 therein so'as to form a substantially closed connector loop, although this is not, of course, necessary in all cases.

The connector bolt 10 may, of course, be arranged within any or; the connector holes t-adyacent the end of the bumper bar and extend into the connector loop so as to cooperate with a connector nut ll arranged within the channel or angle iron bumper bar, if desired, a connector aperture,lsuch as 13, may be formed in the connector loop so as to accommodate this connector nut it and sucient play of the nut may be allowed within this connector aperture so as to make pos sible some adjustment of the connector loop with. respect to the bolt in each of the con nector holes, as indicated in Fig, l. lll'hen the coector bolt is tightened preferably in connection with a loch washer or other hold ing device '12, the connector loo or portion is drawn down tightly against t e cooperat ing flange of the bumper bar and a rigid and secure connection is in this way secured beill As indicated in Fig. l the connector Mill too

lllltl tween the parts For some purposes it is desirable to have the nut ll provided with contact face 21 which may be wedged or forced into holding engagement with the Web 1 of the bumper bar by the action of the bolt and supporting member and thus still more 5 securely hold the parts in this clamped posi-.

tion and minimize movement or loosening thereof. Each of the connector loops or ortions may be clamped to the correspon ing end of the bumper bar in this way and with such a series of connector holes as are indicated an ample range of adjustment is secured so that the attaching members may be clamped at any distance apart necessary to fit the various widths of automobile frames By arranging the connector bolts and co outwardly curving portion 17 of the sup 0 porting member, the end 11 of this resilient strip being, if desired, bent into parallel position so as to form the open connector loop 15 between them of such size as to accommodate the threaded end of the connector bolt 10 used. A similar connector aperture may be formed in this loop portion as indicated so as to accommodate the connector nut 11 and enable the parts to be rigidly clamped together and firmly secure the connector loop against the lower flange 2 of the bumper bar.- If desired a similar adjustment play may be allowed betweenthe nut 11 and the end of the connector aperture 13, so that suitable adjustment is allowed in this way in addition to the adjustment secured by arranging the connector bolt 10 in any one of the different connector holes 4 in the flange 2 of the bumper bar.

This invention has been described in connection with a number of illustrative em bodiments, forms, proportions, parts, arrangements, materials, methods of connection and use, to the details of which disclosure the invention is not of course to be limited, -since what is claimed as new and what is desired to be secured by Letters Patent is set forth in the appended claims.
